The pricing envelope is being pushed on the American Flyer side, too. The latest round of American Flyer Legacy SD70's are essentially $600 MSRP. That's about a 25% increase over when they were introduced in 2012.
Even at the big discounters, they're running around $520, give or take. Plus a scale guy like me also has to add in the price of buying a set of scale wheels, around another 30-40 bucks, plus shipping from Lionel.
Right now, I've been weighing exactly how much I want/need the MKT Heritage unit and currently it's looking like I need it less and less.
